Among the most promising treatments is medical stimulation of ovulation in women who do not ovulate or ovulate irregularly. The best candidates are women who are otherwise normal, and have fertile partners. Serophene_^® or Clomid_^® are two of the most common drugs used for the induction of regular ovulation cycles.

Pergonal_^® is used in replacement therapies for both men and women for replacement of FSH and LH deficiencies (natural gonadotropins or sex hormones). In women, these hormones are essential to the successful development of ovarian follicles, which contain the eggs released at ovulation. In males, these hormones initiate the development and ensure sufficient production of sperm.

Follistim™ is a recombinant follicle-stimulating hormone (FSH) used for the induction of ovulation in women experiencing an absence of ovulation and in women undergoing assisted reproductive technology (ART) procedures. The drug acts like naturally produced FSH by stimulating the development of follicles within the ovary.

Gonal-F_^® is identical to follicle-stimulating hormone (FSH) produced by the pituitary gland. This drug helps to develop eggs in the ovaries and is used as a fertility medicine to develop eggs in women who have not become pregnant because of problems in ovulation.

Antagon_^® is used as a fertility medicine to prevent premature luteinizing hormone (LH) surges in women undergoing the fertility procedure of controlled ovarian hyperstimulation.

Cetrotide_^® is used to block the LH surge during controlled ovarian stimulation prior to Assisted Reproductive Technologies (ART). It prevents premature ovulation in women undergoing controlled ovarian stimulation for ART.

Repronex_^® is a follicle-stimulating hormone (FSH) and luteinizing hormone (LH) that are naturally produced by the pituitary gland. Repronex is used to cause the ovary to produce several follicles, which can then be harvested for use in gamete intrafallopian transfer (GIFT) or in vitro fertilization (IVF).

Profasi_^® contains lutenizing hormone (LH) and is administered at mid-cycle to trigger ovulation of mature eggs.

Letrozole_^® is in a class of drugs known as aromatase inhibitors; it prevents formation of estrogen. Although estrogen is a hormone naturally produced by the body, it can stimulate and maintain the growth of certain types of cancer. Letrozole slows or stops the growth of cancer cells by decreasing the amount of estrogen produced.

If the infertility factor lies with the woman, medical options are generally available and prescribed first. Successful medical and/or surgical treatments are available for many women who have ovulatory, tubal, and cervical barrier problems, including endometriosis, an ovulatory dysfunction, pelvic adhesions, tubal occlusion, or uterine fibroids. If medical and surgical treatment and lifestyle adjustments are unsuccessful, then the next option is the application of advanced reproductive technologies.
